First, the 386's clock pad received an external clock signal at twice the desired frequency. Two transistors were connected as diodes to clamp the signal if it was too high or too low, protecting the chip. 4/11

@aggarwal_pallav Yes. Industrial machinery and issues with ground destroy serial ports quite often.

@JunesPhD General must-haves: DP832 power supply. MSO5000 scope. Fluke 87V DMM. Hakko FX888 soldering iron. Nice desk with overhead. Save the rest of the budget for projects or specialized specialized purposes (RF? SMD Rework station? Through-hole power electronics rework/desoldering?)

@halkyardo Maybe it's not actually quartz clocked? Many line-powered devices use the AC line frequency instead. Not saying it doesn't have quartz in there, but that it might be using it for something else (microcontroller, etc.) and not the actual time.

this is probably, the #1 reason that our impact on the world is so low per capita everyone wants there to be a person on the other side of their publishing, be it papers, or twitter, to take their idea and do the hard work of making something 🤷🏻‍♀️

@tubechip404 Hi, A few of us are playing with Lattice ECP5 FPGAs at our local makerspace in Chicago and we were wondering if we could use multiple BPW34 PIN diodes and try to make something like this. We're working with the OSS-CAD suite and Verilog/LiteX and want to make an MCA.

Did you know that contrary to popular belief, most volcano lairs lack luxuries such as 3-phase power, or even 220V supplies? Today, we rewire this vacuum pump to make do with the accommodations of a geothermal cavern.

Canadian Broadcasting Corp said they’re “less than 70% government-funded”, so we corrected the label

@tubechip404 Would a 4 channel version using a single FPGA benefit at all from the scale?

A sneak preview of OpenKayo, the project that's been consuming far too much time recently: an ESP32-based interface adaptor that turns a @kayosmt Kayo-A4 pick-and-place machine into a simple USB GCode device so it can be controlled by @openpnp

@tubechip404 Hi. I'm interesting in making something like this work with a CZT detector. Would these MCAs work just as well with this type of detector? Do you have any plans to either sell or open source these? I'd be happy to trade some CZT modules for MCA boards! Cheers!

Using this tiny digital multi-channel analyzer, the pulse shape discrimination function was successfully realized. (detector: NaI(Tl), source: Ra-226)

@Betavulgaris6 @MicrochipMakes I think the V is new 3.3V parts (which is the datasheet you are looking at). The ATF150xAS parts you mention are the 5V parts, though, they do have separate pins for Core and IO pwr. Technically, the pins for VccIO aren't documented for the ATF1502:Core and IO is same per sheet

Mad respect for those keeping the internet working during times of war. Mad respect for everyone who is working during these impossible times. I salute you, sir.
